If devin has 3 times as many nickels as quarters and they have a combined value of 200 cents how many of each coin does he have
1 answer:
Devin has 15 nickel coins and 5 quarter coins.
Step-by-step explanation:
Total worth = 200 cents
1 nickel = 5 cents
1 quarter = 25 cents
Let,
Nickels = x
Quarters = y
According to given statement;
5x+25y=200 Eqn 1
x = 3y Eqn 2
Putting x=3y in Eqn 1
Dividing both sides by 40
Putting y=5 in Eqn 2
Devin has 15 nickel coins and 5 quarter coins.
